Answer:
Difference indicates subtraction: The difference of a number and 9 is (x−9) Twice the difference means 2(x−9) We know that the answer to this is 2 , so as an equation: 2(x−9)=2.

Hello
cos ( x + pi/2) =cos(x)cos(pi/2)-sin(x) sin(pi/2)
= cos(x)×0-sin(x) ×1
cos ( x + pi/2) = - sin(x)
The three angles of a triangle should equal 180 so add 52+34 which equals 86.Then subtract 86 from 180 to get the third angles measure which is 94 so the answer is 94.
Answer: 2.592 x 10^6 seconds
Explanation:
There are 3600s in 1 hr
And 24hrs in 1 day which mean
There are 3600 x 24 = 86400s in 1 day
And one month = 30 days
86400 x 30 = 2, 592, 000s in 1 month
Write in scientific notation:
2, 592, 000 = 2.592 x 10^6
The answer would be 10^-3
